MINNESOTA, A COEORATION BOB ROCKER.

Application led April 9, 1927.

My present invention has for its object to provide a bob rocker for the exercise and amusement of children, and to this end it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a side elevation of the bob rocker;

2 is a view in transverse vertical section taken on the line 2--2 of Fig. 1, on an enlarged scale, with some parts broken away; and

Fig. 3 is a fragmentary view partly in side elevation and partly in'longitudinal vertical section taken on the line 3 3 of Fig. 2.

The bob rocker, as shown, comprises rockerequipped end members 4, a seat board 5, and a tie member in the form of a foot rack 6, which members, board, and tie member are in the form of a parallelogram.

Each end member 4 comprises a pair of laterally spaced rockers 7, to the longitudinal centers of which is rigidly securedV and suitably braced a pair of upright posts 8 that are rigidly connected at their vertical centers by a crosstie bar 9. Said posts 8, of each pair, are further connected by upper, lower and intermediate crosstie steel rods 10, 11 and 12. The upper crosstie rods 10 afford handles by which the end members 4 may be rocked. Y

The seatI board 5 is provided'with depending pairs of oilless wood bearings 13 rigidly bolted thereto and journaled on the crosstie rods 12. These bearings 13 extend into notches 14 in the upper edge portions of the crosstie bars 9 and hold the seat board 5 against edgewise shifting movement on the crosstie rods 12.

Stop blocks 15 are bolted to the inner faces of the crosstie bars 9 and are provided with lat oblique upper surfaces 16 arranged to engage the under side of the seat board 5 to limit the rocking movement of the end members 4.

The foot rack 6, as shown, comprises a pair of longitudinally extended bars 17 and spaced foot-engaging bars 18 bolted to the bars 17. The longitudinal bars 17 are provided with bores through which the crosstie rods 11 extend to support the foot rack 6 therefrom.

Serial No. 182,513.

The ends of the longitudinal bars 17 are split to their bores and provided with bolts which hold said ends frictionally clamped onto the crosstie rods 11and thus prevent the foot rack 6 from shifting edgewise on said crosstie rods. The crosstie rods 11 are free to turn in the seats provided therefor in the posts 8.

By reference to Fig. 2 it will be noted that the seat board 5 is considerably narrower than the foot rack 6 so that children sitting astride said board may 'rest their feet on the crosstie bars 18 of the foot rest `6. s

Children sitting on the seat board 5 next to the end members 4 with their feet-engaging the foot rack vwill grasp the handles 10 and impart rocking motion to said end members by means of arm and legv movements. The children sitting on the intermediate portion of the seat board 5 with their feet resting on the foot rack 6 will assist in imparting rocking movements to the end members bymeans of leg movement. As the seat board 5 and foot rack 6 are spaced from the sides of the uprights 8 there is no danger of a child being. pinched or otherwise hurt by the moving parts of the bob rocker.
